FIELD OF THE INVENTION

The present subject matter relates generally to connectors for fiber optic cables.

BACKGROUND OF THE INVENTION

A datacenter may include a large number, e.g., several dozen or even hundreds, of cables, e.g., fiber optic cables or other data cables, connected to a hub such as a headend, a server, or a main distribution frame (MDF). The space within datacenters is at a premium, and the density (amount of connections in a defined space) often limits which type or types of connectors can be used for connecting the fiber optic cables to the hub. One common connector design is referred to as LC connectors. However, such connectors are limited to a count of 144 fibers per panel, e.g., a standard 19″ wide panel with a standard height of 1RU (rack unit), due to the physical size of the connector and the space envelope available. Access to install or remove this type of connector is difficult at high densities.

Some LC connector designs include an extended pulling latch to facilitate removal. However, such extended latches can increase the amount of precious space within the datacenter taken up by each connection. Moreover, the latch mechanisms must be manipulated directly, e.g., by a user's hand or fingers, and therefore accessibility is still an issue.

Improved latching features, e.g., improved accessibility to release the latching mechanism, for various connector types are thus desired.

BRIEF DESCRIPTION OF THE INVENTION

DETAILED DESCRIPTION

Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

As used herein, terms of approximation such as “generally,” “about,” or “approximately” include values within ten percent greater or less than the stated value. When used in the context of an angle or direction, such terms include within ten degrees greater or less than the stated angle or direction, e.g., “generally vertical” includes forming an angle of up to ten degrees in any direction, e.g., clockwise or counterclockwise, with the vertical direction.

FIG. 1 illustrates a push-pull boot connector 100 according to one exemplary embodiment of the present disclosure. FIG. 2 provides an exploded view of the push-pull connector 100 of FIG. 1. As illustrated in FIGS. 1 and 2, the push-pull boot connector 100 is a duplex uniboot connector, e.g., the push-pull boot connector 100 includes two ferrules 208 and a single strain relief boot 300. The push-pull boot connector 100 extends along a longitudinal direction L from a proximal end 102 to a distal end 104. The push-pull boot connector 100 includes a connector housing 200 defining the proximal end 102 of the push-pull boot connector 100 at a first end 202 of the housing 200. A second end 204 of the connector housing 200 is connected to a first end 302 of the strain relief boot 300 and a second end 304 of the strain relief boot 300 defines the distal end 104 of the push-pull connector 100. As will be described in more detail herein, pulling on the boot 300 allows the release of the connector 100 from the adapter 400 (see, e.g., FIGS. 3 and 4). Thus, the connector 100 may be a remote release connector and accessibility to release the connector 100 may thereby be improved.

The strain relief boot 300 may include features to promote ease of manipulating the strain relief boot 300, e.g., for assisting a user in gripping the strain relief boot 300 to push the push-pull boot connector 100 into a connection and/or to pull the push-pull boot connector 100 out of a connection such as when installing or removing the connector in a hub such as a main distribution frame. For example, such features may include one or more ridges 308 at or proximate to the second end 304 of the strain relief boot 300 which provide a profiled edge to assist in gripping the push-pull boot connector 100, e.g., with a user's fingers, at the second end 304 of the strain relief boot 300, which, as noted above, defines the distal end 104 of the push-pull boot connector 100. Accordingly, the push-pull boot connector 100 may be a remote release push-pull boot connector, e.g., in that the user does not need access to the proximal end 102 of the push-pull boot connector 100. Rather, the remote release connector 100 can be released by manipulating the strain relief boot 300, which is remote, e.g., distal, from the point of connection at the proximal end 102 of the push-pull boot connector 100.

As may be seen in FIGS. 1 and 2, the push-pull connector 100 includes a ferrule holder 206 which fits within the connector housing 200. One or more ferrules 208 may be positioned in the ferrule holder 206 of the connector housing 200. As is generally understood in the art, the ferrules 208 are each configured for supporting and aligning an optical fiber (not shown) in order to promote an optical connection of the optical fibers in the ferrules 206 with, e.g., a receptacle in a main distribution frame. The ferrules 208 may be biased forward, e.g., towards the proximal end 102 of the push-pull boot connector 100, by a pair of springs 210, each spring 210 of the pair of springs 210 corresponding to one of the ferrules 208.

As best seen in FIG. 2, the connector housing 200 may further include various internal components for supporting and/or aligning the ferrules 208 and any optical fibers therein, as well as for mounting the push-pull boot connector 100 on a cable containing the optical fibers. For example, such internal components may include a bracket 212, a first collar 214 and a second collar 216. The bracket 212 may be positioned immediately distal of the ferrules 208 and/or the springs 210, e.g., when the internal components are installed within the connector housing 200, such that the springs 210 may bias against the bracket 212 at one end of the springs 210 and against a flange on each respective ferrule 208 at the other end of the springs 210. The collars 214 and 216 may be configured to receive an open end of a cable containing the optical fibers which are received in the ferrules 208 and secure the open end of the cable within the push-pull boot connector 100.

As mentioned above, the connector housing 200 is connected to the strain relief boot 300. Such connection may be a clip-in connection, where the connector housing 200 is connected to the strain relief boot 300 by a clip on one of the strain relief boot 300 and the connector housing 200, and the clip is engaged with a clip mating face on the other of the strain relief boot 300 and the connector housing 200. For example, the strain relief boot 300 may include one or more mating clips 306 (FIG. 2) which are engageable with corresponding clip mating face(s) 218 (FIG. 1) of the connector housing 200. When connected by such a clip-in connection, the connector housing 200 and the strain relief boot 300 may thereby be free to move together along the longitudinal direction L.

As shown in FIG. 3, an example push-pull connection 10 includes the push-pull boot connector 100 and an adapter 400. In various embodiments, the push-pull boot connector 100 also includes a latch release ramp 106 on one of the connector housing 200 and the strain relief boot 300. For example, in the embodiment illustrated in FIGS. 1-4, the latch release ramp 106 is positioned on the connector housing 200.

The adapter 400 includes a channel 406 configured to receive the proximal end 102 of the push-pull boot connector 100 and a latch 408 positioned in the channel 406 of the adapter 400 to engage the push-pull boot connector 100 when the push-pull boot connector 100 moves relative to the adapter 400 in a first direction 1000 along the longitudinal direction L, e.g., into the channel 406 of the adapter 400. For example, in the embodiment illustrated in FIGS. 1-4, the adapter 400 is a dual latch adapter with a pair of opposing latches 408. As shown in FIGS. 3 and 4, the pair of latches 408 are disposed at opposite sides of the channel 406, e.g., a first latch 408 is disposed at the top of the channel 406 and a second latch 408 is disposed at the bottom of the channel 406, e.g., when the push-pull connection 10 is positioned as shown in FIG. 3. The latches 408 may be mirror images of one another, e.g., each latch 408 may extend into the channel 406 from one of the opposing sides towards the other latch 408. The latches 408 may each engage with a recess or notch 220 in the connector housing 200 (FIGS. 1 and 4). Through engagement of the latches 408 with the push-pull boot connector 100, the latches 408 retain the push-pull boot connector 100 in the channel 406 of the adapter 400 when the push-pull boot connector 100 is inserted, e.g., pushed, into the channel 406 of the adapter 400. In embodiments where the latch 408 is a dual latch comprising a pair of opposing latches 408, the push-pull boot connector 100 may include a pair of latch release ramps 106 corresponding to the pair of opposing latches 408. In such embodiments, each latch release ramp 106 of the pair of latch release ramps 106 may be configured to disengage a corresponding latch 408 of the pair of opposing latches 408 from the push-pull boot connector 100 when the push-pull boot connector 100 moves in the second direction 2000 relative to the adapter 400, e.g., when the push-pull boot connector 100 is pulled out of the adapter 400.

The latch release ramp 106 of the push-pull boot connector 100 may be configured to disengage the latch 408 of the adapter 400 from the push-pull boot connector 100 when the push-pull boot connector 100 moves relative to the adapter 400 in the second direction 2000. For example, as best seen in FIGS. 3 and 4, the latch release ramp 106 may be oblique to the longitudinal direction L and may slope towards the distal end 104 of the push-pull boot connector 100. The latch release ramp 106 may extend from a high point at a proximal end of the latch release ramp 106, the proximal end of the latch release ramp 106 being, e.g., an end of the latch release ramp 106 which is closer to or oriented towards the proximal end 102 of the push-pull boot connector 100, to a low point at a distal end of the latch release ramp 106, the distal end of the latch release ramp 106 being, e.g., an end of the latch release ramp 106 which is closer to or oriented towards the distal end 104 of the push-pull boot connector 100. The latch release ramp 106 may be generally oriented or sloped opposite the latch 408, in order to disengage the latch 408 of the adapter 400 from the push-pull boot connector 100 when the push-pull boot connector 100 moves relative to the adapter 400 in the second direction 2000, e.g., when the push-pull boot connector 100 is pulled out of the adapter 400.

FIGS. 5-9 illustrate an additional embodiment of the present subject matter, where the push-pull boot connector 100 is a duplex uniboot connector. As shown in FIG. 6, the push-pull boot connector 100 may include a collar 214 which serves as a crimp for a jacket or strength member of a fiber optic cable. In some embodiments, e.g., as illustrated in FIGS. 7-9, the latch 408 may be a single latch. As shown, the latch 408 also may be provided as a leaf spring within the channel 406. The leaf spring latch 408 of FIGS. 7-9 may be provided as a single latch 408, as shown, or may be provided as a dual latch in other embodiments, e.g., one or more of the dual latches 408 shown in FIGS. 3, 4, 12, 13, 16, and/or 17 may also be provided as leaf spring latches 408.

In the embodiment illustrated by FIGS. 5-9, the latch release ramp 106 is positioned on the strain relief boot 300. As shown, the latch release ramp 106 is positioned on a connector release arm 310 of the strain relief boot 300. In such embodiments, the push-pull boot connector 100 may include a spring 210 positioned generally between the connector housing 200 and the strain relief boot 300, such as between the connector release arm 310 of the strain relief boot 300 and a shoulder 222 on the connector housing 200, e.g., as shown in FIGS. 7-9. The spring 210 may be configured to bias the connector release arm 310 in the first direction 1000. As most easily seen in FIGS. 8 and 9, the connector release arm 310 may be configured to move a fixed distance relative to the connector housing 200 in the second direction 2000. For example, the connector release arm 310 may be biased to or towards a latched position, as shown, e.g., in FIGS. 5 and 8, by the spring 210. The connector release arm 310 may move the fixed distance from the latched position of FIG. 8 to a release position, which is shown in FIG. 9. The fixed distance may be defined by the shoulder 222 on the connector housing 200, where the connector release arm 310 abuts the shoulder 222 when in the release position, as shown in FIG. 9. Once the connector release arm 310 has reached the release position, the connector housing 200 and the strain relief boot 300 may move together in the second direction 2000, e.g., as the push-pull boot connector 100 is pulled out of the adapter 400. Once the pulling force is removed, the spring 210 may be configured to return the connector release arm 310 in the first direction 1000 to the latched position from the release position. As shown in FIG. 9, when the connector release arm 310 is in the release position while the proximal end 102 of the push-pull boot connector 100 is received within the channel 406 of the adapter 400, the latch release ramp 106 biases the latch 408 outward, e.g., away from the push-pull boot connector 100, to disengage the latch 408 from the push-pull boot connector 100.

In some embodiments, e.g., as illustrated in FIGS. 10-13, the push-pull boot connector 100 may be a SC duplex uniboot connector. In such embodiments, e.g., as shown in FIGS. 10-13, the latch release ramp 106 may be provided on the connector housing 200 of the push-pull boot connector 100. In some embodiments, the latch release ramp 106 may be provided proximate the first end 202 of the connector housing 200 and close to the portion of the connector housing 200 in which the ferrule holders 206 are received. As shown in FIG. 11, the push-pull boot connector 100 may include two ferrules 208 and two corresponding ferrule holders 206, with the ferrules 208 biased forward, e.g., to or towards the proximal end 102 of the push-pull boot connector 100, by springs 210 positioned between a flange on each ferrule 208 and a first collar 214. The push-pull boot connector 100 may further include a bracket 212 distal of the first collar 214 and a second collar 216 distal of the bracket 212. One or both of the collars 214 and 216 may be configured to engage and support an end of a fiber optic cable containing the optical fibers which are routed through the ferrules 208. As shown in FIGS. 12 and 13, when the push-pull boot connector 100 moves relative to the adapter 400 in the second direction 2000, e.g., from the installed position shown in FIG. 12 to the release position shown in FIG. 13, the latch release ramp 106 biases the latch 408 outward, e.g., away from the push-pull boot connector 100 along a third direction 3000 which is generally perpendicular to the longitudinal direction L, to disengage the latch 408 from the push-pull boot connector 100.

As another example, the push-pull boot connector 100 may also be a SC simplex connector, e.g., including a single ferrule 208 for a single optical fiber, as illustrated in FIGS. 14-17. In such embodiments, e.g., as shown in FIGS. 14-17, the latch release ramp 106 may be provided on the connector housing 200 of the push-pull boot connector 100. In some embodiments, the latch release ramp 106 may be provided proximate the first end 202 of the connector housing 200 and close to the portion of the connector housing 200 in which the ferrule holders 206 are received.

The present subject matter provides numerous advantages over the prior art, as will be apparent to those of ordinary skill. For example, utilization of an industry standard recognized connector design that has a dual latching feature that does not protrude beyond the body of the connector, therefore minimizing the space required for the connection to occur. This in turn allows a greater density to be mounted within a standard footprint of one rack unit (1RU). The density of a 1RU panel can be increased, e.g., up to 288 fibers. As another example, the combination of a connector variant with a uniboot design minimizes cable volume as compared to a design including more than one boot. Ease of access to install or remove the push-pull boot connector 100 is increased, e.g., in that the installation or removal can be performed by pushing or pulling on the connector boot 300 instead of needing access to the connector housing 200. No remote pulling latch to hinder cable routing or finger access is included. The foregoing are merely examples of potential benefits and advantages the present subject matter may provide and are in no way limiting, the present subject matters may provide additional advantages, and embodiments of the present subject matter may not necessarily include any or all of the specific example advantages described in this paragraph.

The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art.
